We look at the division of 97660781 by 91 
We're looking to find how many times 91 goes into 97660781.

Moving on to step 1:
The number 91 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 91

Moving on to step 2:
The number 91 fits into 97 1 times, leaving a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 6 after subtracting 91 from 97.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 91

Step 3:
If we divide 66 by 91, we get 0 and a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 66, we get 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 91

Advancing to step 4:
If we divide 666 by 91, we get 7 and a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 107.0
Deduct 637 from 666 and we're left with 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 91

Advancing to step 5:
290 divided by 91 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 1073.0
If we subtract 273 from 290, we get 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 91

Let's proceed to step 6:
If we divide 177 by 91, we get 1 and a remainder of 86.
Put 1 as the next digit of the answer. 
Result so far: 10731.0
Subtract 91 from 177 to get 86.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 91

Moving on to step 7:
When dividing 868 by 91, we get 9 with a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 107319.0
If we subtract 819 from 868, we get 49.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 91

Moving on to step 8:
91 goes into 491 5 times with a remainder of 36.
Put 5 as the next digit of the answer. 
Result so far: 1073195.0
Subtract 455 from 491 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
91 can be fit into 360 3 times, resulting in a remainder of 87.
The next digit of our result is 3. 
Result so far: 1073195.3
Subtracting 273 from 360 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 10:
When dividing 870 by 91, we get 9 with a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 1073195.39
Deduct 819 from 870 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 11:
When dividing 510 by 91, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 1073195.395
Subtract 455 from 510 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 12:
The number 91 fits into 550 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 1073195.3956
Subtracting 546 from 550 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
When dividing 40 by 91, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1073195.3956
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
When dividing 400 by 91, we get 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 1073195.395604
If we subtract 364 from 400, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 15:
The number 91 fits into 360 3 times, leaving a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 1073195.3956043
The remainder is 87 after subtracting 273 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 16:
The number 91 fits into 870 9 times, leaving a remainder of 51.
The next digit of our result is 9. 
Result so far: 1073195.39560439
Subtracting 819 from 870 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 1073195.39560439, with a leftover of 5.1e-08.
